To all when it may concern: Be it k1: own thatI, Jorrn' MASLIN, a citisey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Devices for Cleaning WaterMains, of which the following is aspecification. I

; This invention relates-to devices for cleaningwater pipes and mains and has in view the production of a device that is so flexible as to readily pass around the curves and angles of, a water main and at the same time be economical to manufacture, simple. and

strong and easy to be repaired, all as nowwill be described, reference-being had to the fol lowing description, the claims and the drawing, in which Figure 1 is ahorizontal section'of oneof. the hollow bodies with scrapers attached. Fig. '2 is a transverse section of the hollow a body showing the expanded openi'ng. Fig. 3

is a transverse section of the end of the hollow body at which a cable is attached. Fig.

4 is a perspective of the fastening key showing the grooved hollow side. Fig. 5 shows a toothed cutter. Fig. 6'shows a scraper with curved'end. Fig. ;7 ,shows a series of three In the'drawing, Fig. '1,is shown a cylinhollow bodies with cutters and scrapers attached.

drica-l'portion 10 of a hollow body to be attached to a cable by-means of set screws '12, and a'kev 14, the cylinder preferably carrying an er argeme'nt or ridge-10?, in which the set scrc rs and key are located. The expanded portion--11- ofthehollou body, isv

shown .as being of hexagonal contour, and

' atits end rounded so carries cutters and scrapers 18 and 19, attached 'by-means of screws 13. .'The key-14 arallelo'pip'edic' block having has at its endteeth 20'and the scra"er,19 is pipetobecleaned. w 'In practice I' prefer. to have a number-"of hollow bodies carrying toothed cutters' fand "the hollow body.

an es'lual number carrying rounded scrapers. and three carrying scrapers, constitute a ollow bodies, three carrying cutters satisfactory-cleaning dev1ce.- The device is pulled through the pipe to be cleaned by means'of a cable and'the hollow bodies may either be attached to this or to 'a short piece of cable, which is then attachedto the long cable by means of which the device is pulled through the pipe. largement in the opening of the portion 11,

On account of the en the cable isfrec to move laterally, whereby the device isreadily .passed around curves and angles, and thetlatter may even be as small as 90.. v

Inasmuch as the hollow bodies, I'na all be cast'from the same mold they cane pro- .duced very cheaply.- Besides on account of the configuration of these bodies they are verystrong; The "cutters and scrapers 18 and 19' are made of spring'steel, so as to readily pass around permanent obstructions in ipes, and. these cutters and scra ers as as the screws and; blocks areja cheaply and quickly repaired.

this device may be replaced by their usual mechanical equivalents without departing from the'spirit of the invention. i

What I claim as new is:

a hollow body with an opening ex 'anding towards one end. and a key at the ot er end adapted to fasten theh'ollow body to a cable. 2. In a device of the charact'er described,
